Lincoln Electric 250 GXT manual OIL Filter Change, AIR Cleaner and Other Maintenance

Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SG or SH. Always check the API SERVICE label on the oil con- tainer to be sure it includes the letters SG or SH.

SAE 10W-30 is recommended for general, all-tempera- ture use, -5 F to 104 F (-20 C to 40 C).

See Engine Owner’s Manual for more specific informa- tion on oil viscosity recommendations.

Wash your hands with soap and water after handling used oil.

Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take it in a sealed container to your local service station or recycling center for reclamation.

Do not throw it in the trash, pour it on the ground or down a drain.

OIL FILTER CHANGE

1.Drain the engine oil.

2.Remove the oil filter, and drain the oil into a suitable container. Discard the used oil filter.

3.Clean the filter mounting base, and coat the gasket of the new oil filter with clean engine oil.

4.Screw on the new oil filter by hand, until the gasket contacts the filter mounting base, then use an oil fil- ter socket tool to tighten the filter an additional 1/2 to 7/8 turn.

5.Refill the crankcase with the specified amount of the recommended oil. Reinstall the oil filler cap.

6.Start the engine and check for oil filter leaks.

7.Stop the engine, and check the oil level. If neces- sary, add oil to the upper limit mark on the dipstick.

AIR CLEANER AND OTHER MAINTENANCE

•Air Cleaner - With normal operating conditions, the maintenance schedule for cleaning and re-oiling the foam pre-filter is every 25 hours and replace- ment of the air cleaner filter every 100 hours. More frequent servicing is required with dusty operating conditions. Refer to the maintenance section of the Engine Owner’s Manual for more information.

•Refer to the maintenance section of the Engine Owner’s Manual for the maintenance schedule, spark plug servicing, cooling system servicing, and fuel filter replacement.

•Blow out the machine with low pressure air period- ically. In particularly dirty locations, this may be required once a week.

•Output Ranger Selector and Polarity Switches: Switch contacts should not be greased. To keep contacts clean, rotate the switch through its entire range frequently. Good practice is to turn the han- dle from maximum to minimum setting twice each morning before starting to weld.
